Cov Khoom

Sodium hydrosulfite muaj cov khoom siv tshuaj lom neeg tshwj xeeb. Nws tsis ruaj khov heev hauv cov kua dej thiab yooj yim decomposes rau hauv sodium sulfate, sodium sulfide, thiab sulfur dioxide. Cov tshuaj no muaj lub ntsiab lus yaj ntawm 300 ° C thiab lub ntsiab lus kub ntawm 1390 ° C, thiab ruaj khov nyob rau hauv qhuav, qis-kub mob. Txawm li cas los xij, nws yog rhiab heev rau dej noo thiab huab cua, uas ua rau nws decomposition sai dua.

Cov ntawv thov

• Kev Lag Luam Textile: Nws siv tau ua tus neeg sawv cev txo qis hauv cov txheej txheem zas xim, uas ua rau cov xim zas nkag mus rau hauv cov ntaub zoo dua. Nws kuj ua haujlwm ua tus neeg sawv cev dawb rau paj rwb thiab txhob lo lo ntxhuav, ua kom cov ntaub ci ntsa iab thiab pob tshab.

• Kev Lag Luam Ntawv: Sodium bisulfite yog cov tshuaj dawb uas nyiam siv rau cov ntawv ua los ntawm tshuab, thermomechanical pulp, thiab deinked pulp, ua rau cov ntawv dawb thiab zoo dua qub.

• Kev Lag Luam Khoom Noj: Ua ib yam khoom noj ntxiv rau hauv khoom noj, nws ua haujlwm ua ib yam tshuaj dawb thiab tshuaj antioxidant rau cov txiv hmab txiv ntoo qab zib, zaub qhuav, noodles, thiab txiv hmab. Nws pab khaws cov xim khoom noj thiab ua kom lub sijhawm khaws cia ntev dua.

• Kev Tsim Kho Ib Puag Ncig: Hauv kev kho cov dej khib nyiab, sodium metabisulfite txo cov tshuaj lom neeg, pab txhawb rau kev tso tawm cov dej huv dua thiab muaj kev nyab xeeb dua.

• Kev Lag Luam Tshuaj: Nws ua haujlwm ua tus neeg sawv cev txo qis hauv kev tsim cov thiourea thiab nws cov sulfides, ua lub luag haujlwm tseem ceeb hauv ntau yam tshuaj lom neeg.

Ntim Khoom

Kev Khaws Cia

Khaws cia rau hauv qhov chaw qhuav, txias, thiab muaj cua nkag tau zoo ntawm qhov kub ntawm +5°C thiab +30°C. Txhawm rau tiv thaiv kev ua xua tshuaj, tsis txhob kov cov kua qaub muaj zog, cov neeg ua haujlwm oxidizing, dej, thiab dej noo. Thaum kov cov hmoov, hnav hnab looj tes, lub npog ntsej muag, thiab cov tsom iav kev nyab xeeb. Khaws cov khoom no kom deb ntawm cov menyuam yaus thiab cov tsiaj.

Kev Thauj Mus Los

Vim tias cov khoom no rhiab heev rau cov dej noo thiab huab cua, uas yuav ua rau muaj cov pa roj sulfur dioxide (SO₂), yuav tsum muaj kev nyab xeeb thaum thauj mus los.
